[popis] => The effect of subcritical crack growth is nowadays intensively studied mainly in relation to the strength of ceramic materials. The main aim of the contribution is to describe behavior of micro-crack propagating in the Low Temperature Co-fired Ceramics (LTCC) under subcritical crack growth (SCCG) conditions. The micro-crack behavior is significantly influenced by residual stresses developed in the LTCC due to different coefficients of thermal expansion of individual components. Two-dimensional numerical model was developed to simulate micro-crack propagation through the composite. The micro-crack propagation direction was determined using Sih’s criterion based on the strain energy density factor and the micro-crack path was obtained. The residual lifetime of the specific ceramic particulate composite (LTCC) was estimated on the basis of experimental data. The paper contributes to a better understanding of micro-crack propagation in particulate ceramic composites in the field of residual stresses.

[popis] => A micro-crack propagation in particulate ceramic based composite was studied using finite element method (FEM). Subcritical crack growth (SCG) was numerically simulated under complex load conditions (mechanical loading and loading by internal residual stresses). The effect of residual stresses on the crack propagation was studied. Two-dimensional computational model of particulate ceramic composite with material properties corresponding to low temperature co-fired ceramics (LTCC) was developed. The results indicate that the presence of residual stresses significantly reduces values of stress intensity factor in the vicinity of composite surface and the direction of residual stresses around the particles contributes to the micro-crack deflection from the particles. The time to failure of the composite under mechanical loading was determined. Results obtained contribute to a better understanding of the role of residual stresses during micro-crack propagation in ceramic particulate composites.

[popis] => A crack propagation and fracture behaviour of particulate ceramic composite were investigated. Influence of 3D shape of particles on the crack propagation was studied together with influence of the presence of residual stresses, which are developed inside the composite during manufacturing process. Finite element (FE) method was used for numerical simulation of propagating crack in the composite. Basic numerical models of low-temperature co-fired ceramics (LTCC) with alumina particles homogenously dispersed in the glass matrix were developed. Volume fraction of alumina phase was 20vol.%, which is typical amount for LTCC. The results show that existence of residual stresses retards the crack propagating under conditions of sub-critical crack growth (SCG). Presented results contribute to a better understanding of the role of residual stresses in particulate ceramic composites.

Basic numerical models of low-temperature co-fired ceramics (LTCC) with alumina particles homogenously dispersed in the glass matrix were developed. Volume fraction of alumina phase was 20vol.%, which is typical amount for LTCC. The results show that existence of residual stresses retards the crack propagating under conditions of sub-critical crack growth (SCG). Presented results contribute to a better understanding of the role of residual stresses in particulate ceramic composites.

[duvernost_udaju_id] => S
[popis] => The highly anisotropic interactions in organic semiconductors together with the soft character of organic materials lead to strong coupling between nuclear vibrations and exciton dynamics, which potentially results in anomalous electrical, optical and optoelectrical properties. Here, we report on the Raman antenna effect from organic semiconducting nanobelts 6,13-dichloropentacene (DCP), resulting from the coupling of molecular excitons and intramolecular phonons. The highly ordered crystalline structure in DCP nanobelts enables the precise polarization-resolved spectroscopic measurement. The angle-dependent Raman spectroscopy under resonant excitation shows that all Raman modes from the skeletal vibrations of DCP molecule act like a nearly perfect dipole antenna IRaman ∝ cos4(θ − 90), with almost zero (maximum) Raman scattering parallel (perpendicular) to the nanobelt's long-axis. The Raman antenna effect in DCP nanobelt is originated from the coupling between molecular skeletal vibrations and intramolecular exciton and the confinement of intermolecular excitons. It dramatically enhances the Raman polarization ratio (ρ = I‖/I⊥ > 25) and amplifies the anisotropy of the angle-dependent Raman scattering (κRaman = Imax/Imin > 12) of DCP nanobelts. These findings have crucial implications for fundamental understanding on the exciton–phonon coupling and its effects on the optical properties of organic semiconductors.

[nazev_orig] => Two-dimensional finite element model of vowel production: properties of self-oscillating vocal folds interacting with fluid flow
[duvernost_udaju_id] => S
[popis] => The current study concerns finite element (FE) model of flow-induced self-sustained oscillation of the human vocal folds (VF) in interaction with vocal tract (VT) acoustics. Two dimensional (2D) FE model consists of the fluid model (involving the VT and trachea) and the structure model (the VF). Geometry of the VT was converted from magnetic resonance images (MRI) data for production of a Czech vowels. The VF model is based on widely used Scherer’s M5 geometry with four-layered structure comprising epithelium, superficial lamina propria (SLP), ligament and muscle.

[nazev_orig] => The Original Method for Assessment of Residual Stresses in Reinforced Surface Layers
[duvernost_udaju_id] => S
[popis] => An original method was recently developed for an assessment of residual stresses in case-hardened steels
based on S-N curves of hardened and virgin samples along with the measurement of location of fish-eye
crack centres. This method is applicable only when the surface of virgin specimens is sufficiently smooth to
avoid the initiation of fatigue cracks from large surface defects. A systematic study focused on identification
of the applicability range was started using specimens with extremely rough surfaces finished by turning. The
analysis yielded compressive stresses up to 700 MPa at the hardened surface and high tensile stresses up
to 500 MPa in the specimen bulk. The most probable location of fish-eye centres was, however, predicted to
be in a significantly higher depth than that found in the real specimens. This could be attributed to the large
surface damage induced by turning which, therefore, lies beyond the acceptable range of surface machining.

[popis] => The Selective Laser Melting (SLM) is an advanced technology of producing three-dimensional solid objects
by 3D printing from a digital file. The article deals with fatigue push-pull testing of SLM samples to determine
the dependence of their fatigue characteristics on the orientation of laser melted layers to the loading axis,
the hatch spacing of the laser beam and the surface roughness of 3D printed objects. The results revealed
that the transverse orientation of layers (90° to the loading axis) led to a defect type of fracture and to a lower
fatigue life than that exhibited by both the horizontal (0°) and inclined (45°) orientations. The standard hatch
spacing led to a higher fatigue life than the reduced one. The samples with machined and polished surfaces
revealed, due to their very small averaged surface roughness, a much better fatigue resistance than that
exhibited by the as-built specimens.

[nazev_orig] => Effect of Martensitic Transformation on Local Stresses and Strains at a Notch of Cyclically Loaded Superelastic NiTi Ribbon
[duvernost_udaju_id] => S
[popis] => Reversible and volume preserving martensitic transformation /MT/ proceeding in shape memory alloys such as NiTi differs from that in steels. Especially in superelastic NiTi largely used in medical devices, the effect of MT on the material response at stress risers and the role of MT in crack nucleation and propagation remain unclear and widely unexplored. Therefore, we studied the effect of MT on the stress and strain fields around a notch of a superelastic NiTi ribbon thus mimicking in a simplified manner mechanics at stress risers of geometrically complex medical devices such as stents or at crack tips of fatigue damaged NiTi elements. We used digital image correlation /DIC/ to track strains around a notch of a NiTi during superelastic. As for the stress evaluation, we used finite element analysis (FEA) coupled with a SMA material model implemented using a user subroutine. In summary, we found that the effect of MT proceeding in NiTi at a constant plateau stress is threefold. First, MT is triggered locally at the notch where it acts as a stress reliever as MT proceeds at a constant stress. Second,
MT further propagates into the bulk that leads to high deformations of martensitic phase at already transformed material in the vicinity of the notch. Third, MT acts again as a stress reliever at the notch once it propagates macroscopically along the length of the sample through a shear band at a constant plateau stress.

We used digital image correlation /DIC/ to track strains around a notch of a NiTi during superelastic. As for the stress evaluation, we used finite element analysis (FEA) coupled with a SMA material model implemented using a user subroutine. In summary, we found that the effect of MT proceeding in NiTi at a constant plateau stress is threefold. First, MT is triggered locally at the notch where it acts as a stress reliever as MT proceeds at a constant stress. Second,
MT further propagates into the bulk that leads to high deformations of martensitic phase at already transformed material in the vicinity of the notch. Third, MT acts again as a stress reliever at the notch once it propagates macroscopically along the length of the sample through a shear band at a constant plateau stress.

[popis_en] => Reversible and volume preserving martensitic transformation /MT/ proceeding in shape memory alloys such as NiTi differs from that in steels. Especially in superelastic NiTi largely used in medical devices, the effect of MT on the material response at stress risers and the role of MT in crack nucleation and propagation remain unclear and widely unexplored. Therefore, we studied the effect of MT on the stress and strain fields around a notch of a superelastic NiTi ribbon thus mimicking in a simplified manner mechanics at stress risers of geometrically complex medical devices such as stents or at crack tips of fatigue damaged NiTi elements.

[popis] => The contribution is related to experiments on near-threshold fatigue cracks under shear modes II, III and II+III in bcc metals. Cylindrical bars with circumferential cracked notch were loaded by shear force. The notch is located in the cross-section where no bending moment is present and it is loaded in pure shear. In-plane pre-cracks with microtortuous crack front were created by compressive cyclic loading in mode I to obtain smooth fracture surfaces and, consequently, the effective values of crack driving force could be measured. The circumferential
pre-crack front could be modelled as a serrated front of a linear roughness identical to the real one. As reported elsewhere, the fatigue crack in bcc metals loaded under shear modes II, III and II+III always grows by creation and coalescence of local tongues loaded in mode II. Therefore, the aim of the model was to calculate the local stress intensity factor k 2 as a driving force for fatigue crack initiation and growth along the whole serrated crack front.

[popis] => Osseointegration is paramount for the longevity of dental implants and is significantly influenced by biomechanical stimuli. The aim of the present study was to assess the micro-strain and displacement induced by loaded dental implants at different stages of osseointegration using finite element analysis (FEA). Computational models of two mandible segments with different trabecular densities were constructed using microCT data. Three different implant loading directions and two osseointegration stages were considered in the stress-strain analysis of the bone-implant assembly. The bony segments were analyzed using two approaches. The first approach was based on Mechanostat strain intervals and the second approach was based on tensile/compression yield strains. The results of this study revealed that bone surrounding dental implants is critically strained in cases when only a partial osseointegration is present and when an implant is loaded by buccolingual forces. In such cases, implants also encounter high stresses. Displacements of partially-osseointegrated implant are significantly larger than those of fully-osseointegrated implants. It can be concluded that the partial osseointegration is a potential risk in terms of implant longevity.

[popis] => This work introduces a methodology on how to incorporate complex inner metallic structure of LTCC (eventually PCB) components into an FE model in order to capture its influence on the surrounding critical parts such as solder joints or attached electronic components. To this end a homogenization technique, combining properties of several materials into effective properties of one “artificial” material, was utilized. For each element of the FE model, the effective elastic and thermal properties, obtained based upon the volume content of silver (eventually other material) in the volume of a given finite element, were calculated and prescribed. To demonstrate and quantify the influence of such homogenized properties of LTCC structure on the surrounding components, both versions of the LTCC components, i.e. bulk and homogenized, were subsequently subjected to the thermal cycle loading . The results show that the thermal cycle simulation of the system containing an LTCC with (i) bulk and (ii) homogenized properties deliver the same position of the critical solder joint between PCB and LTCC component. Nevertheless, significant stresses are induced inside the LTCC component considering the internal metallization, which might be responsible for its earlier failure in comparison with predictions made just based upon the bulk LTCC model.
